BY q'dw' Patented Aug. 27, 1946 IFOLDABLE END WALL CARRIER AND oARToN William A. Ringler, Wayne,'Pa., assignor to The Gardner-Richardson Company, Middletown, Ohio, a corporation of Ohio I Application January 15, 1942, Serial No. 426,893

.My invention relates to bottle carriers and other packaging carriers and cartons in which the completed flat structure may be erected and completed by the folding of integral portions thereof in such a way as to form end straps or end walls. at the time of insertion of the material or articles to be packaged.

I have illustrated my invention in a form suitable for a bottle carrier.

In its essentials, the novelty of my construction lies in the formation of the foldable ends, by slitting them out of the body of a blank and articulating them in such a way that they may be folded about theedges of the side walls of the carrier, with the outer finish of the board, outermost. By forming the foldable endwalls as will be described, the material is slit from portions of the material within the confines of the side margins of the side walls. This effects a great saving of board, and enables me to provide perfectly adequate packages for many articles with substantial savings, which in the present Fig. 3 illustrates in the flat a first fold in the formation of the article for shipment.

Fig. 4 shows the second fold.

Fig. 5 shows the third fold.

Fig. 6 is a perspective of the carrier folded for shipment.

Fig. 7 is a perspective showing the end wall or strap portions unfolded preparatory to erectin the carrier.

Fig. 8 is a perspective showing the end strap portions twisted outwardly to set them up ready for final erection of the carrier.

Fig. 9 is a perspective of the carrier fully erected, with .handle in place ready for insertion of bottles. 7

Referring to Figs. 1 through 9, the blank for the bottle carrier is shown in Fig. 1 having a portion I, to become the base of the carrier, portions 2 and 3 to become the side walls thereof, and portions 4 and 5 to become handle receiving projections from the side walls proper. Score lines dotted as at 2a, 3a, define the beginning of the side walls, and an intermediate score line 6 Claims. (Cl. 224-45) 2 6, crossing the base portions serves a purpose to be described below.

The end wall forming elements are formed in the blank by two elongated slitted portions I and 8, connected at their ends to the body of the blank. This connecting portion is scoredin triangular form by means of score lines la, defining the ends of the slitted or strap portions, 8a defining a triangle in connection therewith, and the slit line which is nearest in each case to the outer edge of the blank.

The portions 4 and 5 are scored so as to fold inwardly into overlapping triangular form, so that holes 4a, punched in the three overlapping portions are ready for receipt of a handle for the carrying of the device. v

The structure may be understood from the mode of erecting it. .As a first operation, shown in Fig. 3, the blank is folded on the line 2a. Then the folded over portion is folded back on the line 6 as shown in Fig. 4. Thereafter the final fold is along the line 3a and the result is a folded carrier as shown in Fig. 5, a perspective of which is shown in Fig. 6. I I

To set up the device, the folded carrier is opened and the two end strap portions pushed down onthe median score line B. This brings the two straps to a depending position. ,They are then twisted or folded outwardly and upwardly whereupon they bend on the score lines 8a, as shown in Fig. 8. If desired, adhesive may be placed as at 9, to secure the end straps in position upon folding them or setting them up as described. The folded or set up condition is shown in Fig. 8.

When the end straps or walls have been set into place, as now described, the carrier may be opened, to the position shown in Fig. 9, whereupon it is ready for insertion of bottles and a handle H). In the form where the end straps are cemented down, they can be tucked into the carrier from the sides to make a compact shipping package, simply reversely bending the score line 6.

It may be noted that the face of the paper board making up the carrier is brought outermost by the procedure noted, so that board may be used which is economical due to being finished with special coating calendaring, etc., on one face only.

are foldable end walls for a carrier whether of three walls or four, which foldable end Walls are out from portions of the general body of the blank, and are connected to the blank by triangular scored portions in which the'attaching line or line of articulation is normal to the lengthwise extension of the end wall members,

The result of this arrangement is that the foldblank intermediate the edges thereof, each of said slits beginning intermediate one of the side walls, extending across the bottom wall and terminating intermediate the other side wall, said slits dividing the bottom wall and portions of the side Walls into five parallel strips, diagonal score lines being formed in the strips demarked by each pair of slits at the ends thereof, the proportion- .ing of the parts bein such that when the said side walls are erected at right angles to the bottom wall, the strips demarked by the last mentioned pair of slits may be folded outwardly and able end walls can be cut from the main body of the blank, and when set up will have the finished or when printed or colored th'e printed and colored face of the paper board turned outwardly.

Having'thus described certain examples of my invention what I claim as new and desire to secure by Letters Patent is:

1. In a folding carton or carrier, a central wall and two side walls, the said side walls being articulated to the central wall along parallel score lines, one On each side of the central wall, two parallel pairs of straight slits being formed in said side and central walls, each of said slits beginning intermediate one of the side walls, extending across the central wall, and terminating intermediate the other side wall, said slits demarking strips of the material of said walls, which strips are articulated at their ends to the said side walls, each such strip having at each end a diagonal score lineextending across it, and the proportioning of the parts being such that when the said side walls are erected at right angles to the said central wall, one of said strips may be brought outwardly at each end of the'central wall, to a position in which the said strip is oriented in, planes substantially at right angles to the said central wall, a central portion of each strip extending across between the two side walls, the first mentioned score lines where they extend across said strips coinciding substantially with the ends of the side walls and remaining portions of said strips lapping outside the side walls, whereby to retain the side walls in erected condition with respect to said central wall, the said central wall and portions of said side walls in the erected structure being formed of three spaced 7 strips.

2. In a bottle carrier or like structure an elongated blank of flexible material comprising a bottom wall and two side walls, one of the side walls being articulated to the bottom wall, on each side of it, along a score line extending across said blank, said score lines being parallel, two pairs of straight and parallel slits being formed in said upwardly into planes lying substantially at right angles to said bottom wall, portions of said strips formedfrom thebottom wall extending in erected condition from one side wall of the structure to the other. and forming end walls therefor, the parallel score lines in said portions substantially coinciding with the ends of said side walls, and. remaining portions of said strips lapping outside the side walls so as to retain said side walls in erected condition, the bottom wall and portions of said side walls in the erected structure being formed from the remaining threepf the aforementioned strips.

3. The structure claimed in claim 2 in which a score line passes centrally through said bottom wall parallel to the first mentioned score lines and crossing each of the said strips, so as to provide for the collapse of the erected structure.

4. The structure claimed in claim '2 wherein the ends of the said blank, in the side wall portions, are provided with diagonal scorelines beginning at the sides of the blank and meeting centrally at the edges thereof, whereby, triangular end portions of said blank maybe folded over on said side Walls to reinforce the ends thereof.

5. The structure claimed in claim 2 wherein the ends of the said blank, in theside wall portions, are provided with diagonal score lines 'beginning at the sides of the blank andmeeting centrally at the edges thereof, whereby triangular end portions of said blank may be folded over on said side walls to reinforce the ends thereof, the said side walls being provided with mating perfo rations for the acceptance of a handle structure whereby the carrier may be lifted. V

6. The structure claimed in claim 2 wherein the ends of the said blank, in the side wall portions, are provided with diagonal score lines be: ginning at the sides of the blank and meeting centrally at the edges thereof, whereby triangular end portions of said blank maybe folded over on said side walls to reinforce the ends thereof, the said side walls being provided with mating perforations for the acceptance of a handle structure whereby the carrier may be lifted, the said bottom wall having a central score line parallel to the first mentioned score line and extending across all of the said strips, whereby the erected structure may be collapsed.
